Step-out provided by the embodiments of the present application determines method, suitable for the scene that same frequency continuously covers, wherein due to a Other base station clock step-out, periphery can be caused to synchronize, and base station is interfered or the base station of step-out itself is interfered, and commonly uses really It is lost if the mode for determining step-out is the timing reference input in base station, it will usually have corresponding alarm prompt, to pass through alarm prompt Determine the base station of step-out, in addition, the base station of step-out can do corresponding re-synchronization or reset operation, and timing reference input After the time of loss is more than the preset period, base station will automatically close up contained fan, to prevent base station adjacent with frequency to other Cell interferes.However, if timing reference input is normal, but when leading to base station due to software defect or back end device failure It when clock step-out, will be unable to carry out alarm prompt, will be unable to the base station for finding step-out at this time, so as to cause the accuracy of step-out is determined It is poor.
Therefore, step-out provided by the present application determines method and apparatus, it is intended to solve to determine the base station of step-out in the prior art When error it is larger, the poor technical problem of accuracy.
The technical solution of the application is described in detail with specifically embodiment below.These specific implementations below Example can be combined with each other, and same or analogous concept or process may be repeated no more in some embodiments.
Fig. 2 is the flow diagram that step-out provided by the embodiments of the present application determines embodiment of the method one.The embodiment of the present application It provides a kind of step-out and determines method, this method can determine the device of method by arbitrarily executing step-out and execute that the device can To pass through software and or hardware realization.In the present embodiment, which can be integrated in control network element.As shown in Fig. 2, this reality The method for applying example may include：
Step 201, control network element receive the interference index that N number of base station is sent.
Wherein, interference index includes the first interference and noise (Interference and Noise；IN) IN1, second dry Disturb and noise IN2 and third interference with noise IN3, wherein first interference with noise, second interference with noise and third interference with Noise is the interference that sub-frame of uplink distinct symbols are subject to respectively.In addition, N is positive integer.
Step 202, control network element determine from the neighboring station of N number of base station and/or N number of base station M the based on the interference index One base station to be checked.
In the present embodiment, N number of base station will monitor the interference index of all cells of our station respectively, when finding that there are some is small When the interference index in area is more than predetermined threshold value, need the interference of cell level to be aggregated into base station level, and on control network element Report IN1, IN2 and IN3, wherein IN1, IN2 and IN3 are respectively the interference on distinct symbols.Specifically, typically with base station or Frequency point rank is reported, if frequency point is identical, i.e., when a central point in frequency range is identical, base station will report disturbed strongest Cell index.If have multiple frequency points under a base station, it will be reported to control network element by multiple messages, or can pass through The a piece of news for carrying multiple frequency point informations is reported to control network element.
It, will be from the neighboring station of N number of base station and/or N number of base station after control network element receives the interference index that each base station reports Determine that M the first base station to be checked carries out subsequent detection, due to base station and synchronous base station interference character position and the spy of step-out Sign has differences, it is possible to be to determine each base station according to features such as interference character position, interference strength, interference base station numbers No step-out selects the first base station to be checked with this.
Wherein, it is to find the interference of clock step-out that base station, which monitors and reports the major function of interference index, and detection trigger, together When avoid other interference triggering detection of loss of mains flows again, wherein other interference include atmospheric duct and what major issue generated does Feature is disturbed, major issue is usually Bulk Call event, and specifically, base station needs to sentence before interfering index to control reported by network elements The disconnected interference index detected is more than whether pre-determined threshold is to be caused by atmospheric duct or major issue, if it is by atmospheric duct or Interference lifting caused by major issue, then base station is not to control reported by network elements interference index.
In addition, control network element determined from the neighboring station of N number of base station and/or N number of base station the first base stations to be checked M include with Lower three kinds of situations：(1) control network element determines M the first base stations to be checked from N number of base station；(2) network element is controlled from N number of base station M the first base stations to be checked are determined in neighboring station；(3) control network element determines M the from the neighboring station of N number of base station and N number of base station One base station to be checked.
If due to occurring clock step-out and to generate interference, then certainly exist last several symbols of base station sub-frame of uplink by To (may be that synchronous base station is disturbed, it is also possible to which the base station of step-out is disturbed) the phenomenon that interference, so, if it find that having Last several symbols of base station sub-frame of uplink are interfered, then may determine that there may be clock step-outs at this time, and therefore, base station needs The disturbed condition of all cells of our station is detected in each period.
Fig. 3 is the schematic diagram of the average interference power of sub-frame of uplink, and Fig. 4 is the signal of the average interference power of sub-frame of uplink Figure, as shown in Figure 3 and Figure 4, base station each period can calculate the uplink interference average value of distinct symbols, if there is some cell Average interference power on last several symbols of the last one sub-frame of uplink is more than thresholding, then illustrates the interference characteristic of the cell Meet clock step-out interference characteristic.In the present embodiment, base station each period can calculate the interference on IN1, IN2 and IN3, if IN3 average interference powers on the time slot 1 (Slot1) of the last one sub-frame of uplink are more than thresholding, and judge not being major issue Caused interference lifting, then IN1, IN2 and IN3 are reported to control network element by base station.It is worth noting that, being in the present embodiment It is illustrated with the case where proportioning 1 and proportioning 2, in practical applications, the present embodiment is all suitable for for arbitrarily matching.
In addition, it is necessary to explanation, as Figure 3-Figure 4, IN2 can also be the preceding several of the last one subframe Slot0 Symbol, such as preceding 4 symbols of Slot0.Fig. 3 and Fig. 4 show a complete Slot0, wherein general cyclic prefix (Normal CP) is 7 symbols, and extended cyclic prefix (Extended CP) is 6 symbols.After IN3 can also be Slot1 It is a complete Slot1 in several symbols, such as 4 symbols, Fig. 3 and Fig. 4.
In addition, when the base station clock of step-out shifts generation interference, the base station of step-out is being interfered with synchronous base station Intensity, interference character position, interference base station quantitative aspects can have differences, and the base of step-out can be directly found by these features Stand or reduce step-out base station range.In practical applications, determine that the first base station to be checked may include following several situations：
The first：If N is less than predetermined threshold value, controls network element and N number of base station is determined as the first base station to be checked.
Specifically, Fig. 5 is the schematic diagram that base station reports interference index, as shown in figure 5, those skilled in the art can manage It solves, last several symbols (8,9,10,11,12,13) in step-out base station sub-frame of uplink 2 (U) receive synchronous base station 1, synchronize The interference of base station 2 and the downlink subframe 3 (D) of synchronous base station 3, i.e. last several symbols in step-out base station Slot1 are interfered, In conjunction with shown in Fig. 2 and Fig. 3, i.e. the IN3 of the only base station of step-out is interfered, and usually only the base station of step-out can be interfered Report.Therefore, if within some period, the quantity of the base station of index is interfered to be less than predetermined threshold value to control reported by network elements, i.e. N is less than When predetermined threshold value, it may be considered that report interference index there are the possibility of step-out for N number of base station, at this point it is possible to will directly report This N number of base station of interference index is determined as the first base station to be checked, and in this case, N is equal to M.Wherein, predetermined threshold value can root It is configured according to actual conditions or experience, such as could be provided as 1 or 2 etc., for the specific value of predetermined threshold value, this implementation This is not restricted for example.
Second：If N is greater than or equal to predetermined threshold value, judge whether IN1, IN2 and IN3 of N number of base station are big respectively In pre-determined threshold；If IN1, IN2 and IN3 of N number of base station are all higher than pre-determined threshold, control network element according to interference index IN1, Preceding M base station is determined as the first base station to be checked by the sequence of the average value of IN2 and IN3 from big to small.
Specifically, Fig. 6 is the schematic diagram that base station reports interference index, as shown in fig. 6, those skilled in the art can manage Solution, synchronous base station 1, synchronous base station 2 and rear several symbols of the special subframe 1 (S) of synchronous base station 3, sub-frame of uplink 2 (U) by The interference of step-out base station down subframe 0 (D), i.e., synchronous base station 1, synchronous base station 2 and the Slot0 and Slot1 in synchronous base station 3 Be interfered, in addition, rear several symbols of the special subframe 1 (S) of step-out base station, sub-frame of uplink 2 (U) receive synchronous base station 1, The interference of synchronous base station 2 and 3 downlink subframe 3 (D) of synchronous base station, in conjunction with shown in Fig. 2 and Fig. 3, under this scene, due to synchronous Base station is similar with the base station interference characteristic of step-out, is all that IN1, IN2 and IN3 are interfered, the base station of synchronous base station and step-out Interference will be carried out to report.Therefore, if within some period, to control reported by network elements interfere index base station quantity be more than or It is default then to judge whether IN1, IN2 and IN3 of each base station are all higher than when i.e. N is greater than or equal to predetermined threshold value equal to predetermined threshold value Thresholding will select the strongest M base station of average interference to be determined as if IN1, IN2 and IN3 of each base station are all higher than pre-determined threshold First base station to be checked, the i.e. sequence according to the average value of interference index from big to small, are determined as the first base to be checked by preceding M base station It stands, such as：According to the average value sequence from big to small of IN1, IN2 and IN3, preceding M base station is determined as the first base station to be checked. Wherein, predetermined threshold value for example can be 2.
The third：If N is greater than or equal to predetermined threshold value, and the IN1 of N number of base station is less than pre-determined threshold, then controls network element point Not Que Ding N number of base station neighboring station and N number of base station neighboring station relationship quantity quantity；Network element is controlled according to neighboring station relationship quantity from more To few sequence, preceding M base station is determined as the first base station to be checked, wherein neighboring station relationship includes the neighboring station of each base station and N number of base Neighboring station relationship between standing.
Specifically, Fig. 7 is the schematic diagram that base station reports interference index, as shown in fig. 7, those skilled in the art can manage Solution, synchronous base station 1, synchronous base station 2 receive step-out base station down with rear several symbols of the sub-frame of uplink 2 (U) of synchronous base station 3 The interference of subframe 3 (D), i.e., synchronous base station 1, synchronous base station 2 are interfered with the Slot1 in synchronous base station 3, in conjunction with Fig. 2 and Fig. 3 It is shown, in such a scenario, since the IN3 of only synchronous base station is interfered, so only synchronous base station can be interfered Report.Therefore, if within some period, the quantity of the base station of index is interfered to be greater than or equal to predetermined threshold value to control reported by network elements, And the IN1 of each base station be less than pre-determined threshold when, the first base station to be checked will select in the neighboring station of each base station, actually answer In, control network element will determine the neighboring station relationship quantity of the neighboring station and N number of base station of each base station respectively, and by neighboring station relationship quantity M most base stations is determined as the first base station to be checked.Wherein, predetermined threshold value is such as can be 2.
For example, if M is 2, it is assumed that N number of base station is respectively the base stations A, the base stations B, the base stations C, the base stations D and the base stations E, wherein The neighboring station of the base stations A is the base stations a, the base stations b and the base stations c, and the neighboring station of the base stations B is the base stations a, the base stations d and the base stations c, and the neighboring station of the base stations C is The neighboring station of the base stations A, the base stations a, the base stations b and the base stations d, the base stations D is the base stations A, the base stations a, the base stations c and the base stations d, and the neighboring station of the base stations E is A Base station, the base stations B, the base stations b, the base stations c, the base stations e, the base stations f, the base stations g, the base stations h and the base stations i, the then base stations a and the base stations A, the base stations B, C There are neighboring station relationships for base station and the base stations D, and therefore, the neighboring station relationship quantity of the base stations a is the base stations 4, b and the base stations A, the base stations C and the base stations E There are neighboring station relationships, and therefore, the neighboring station relationship quantity of the base stations b is 3, with similar mode, determines the neighboring station relationship number of the base stations c It is the neighboring station relationship quantity of the base stations 3, e be the neighboring station relationship quantity of the base stations 1, f is 1, g that amount, which is the neighboring station relationship quantity of the base stations 4, d, It is the neighboring station relationship quantity of the base stations 1, i is 1 that the neighboring station relationship quantity of base station, which is the neighboring station relationship quantity of the base stations 1, h, determines neighbour After relationship of standing quantity, control network element, from more to few sequence, the base stations a and the base stations c will be determined as according to neighboring station relationship quantity First base station to be checked.
4th kind：If N is greater than or equal to predetermined threshold value, network element being averaged according to interference index IN1, IN2 and IN3 is controlled The sequence of value from big to small, it is by preceding L base station, and according to neighboring station relationship quantity from more to few sequence, preceding P base station is true Be set to the first base station to be checked, wherein neighboring station relationship includes the neighboring station relationship between the neighboring station and N number of base station of each base station, L and P is integer, and L and P's and is equal to M.
Specifically, if within some period, the quantity of the base station of index is interfered to be greater than or equal to control reported by network elements pre- If threshold value, i.e. when N is greater than or equal to predetermined threshold value, then the first base station to be checked will include two parts, and first part can be according to the Two kinds of modes selects preceding L base station as the first base station to be checked that is, according to the average value sequence from big to small of interference index, Preceding P base station can be determined as according to neighboring station relationship quantity from more to few sequence by second part according to the third mode First base station to be checked, wherein specific method of determination is similar with the third mode with the second way, and details are not described herein again.
Step 203, control network element determine P the second base stations to be checked；The P the second base stations to be checked are to be checked from M a first That is selected in base station meets the base station of testing conditions, and testing conditions are that the first base station to be checked is broadcasted in the designated position of radio frames Characteristic sequence cannot by neighboring station the designated position receive.
Wherein, P is integer, and P is less than or equal to M.In the present embodiment, control network element determines M the first base stations to be checked Later, the second base station to be checked will be selected from the neighboring station of M the first base stations to be checked and each first base station to be checked.In practical application In, the principle of clock stringent synchronization, predeterminated position hair of first base station to be checked in default radio frames can be required according to TDD system Characteristic sequence is sent, if synchronous, the neighboring station of the first base station to be checked will can be normally received in the predeterminated position of default radio frames To this feature sequence；If step-out, because missing reception detection window, the neighboring station of the first base station to be checked is caused to will be unable to detect Characteristic sequence.
Similar, the neighboring station of the first base station to be checked sends characteristic sequence, and the first base station to be checked detects sequence, can also sentence Fixed first base station synchronization to be checked.If the characteristic sequence neighboring station that the first base station to be checked is sent can not all receive, and neighboring station is sent out The characteristic sequence sent, the first base station to be checked can not also receive, then judge the first base station to be checked may step-out, be determined as the Two base stations to be checked.
In the present embodiment, when the neighboring station of the first base station to be checked is also simultaneously the first base station to be checked, feature sequence can be just sent Row, that is to say, that only have the first base station to be checked that can just send characteristic sequence in the present embodiment, but the application does not limit and only has First base station to be checked just sends the situation of characteristic sequence.Characteristic sequence is sent for neighboring station, the first base station to be checked receives feature sequence The mode and principle of row send characteristic sequence with the first base station to be checked, and the mode that neighboring station receives characteristic sequence is similar with principle, this Place repeats no more.
Optionally, Fig. 8 is the flow diagram that control network element provided by the embodiments of the present application determines the second base station to be checked, such as Shown in Fig. 8, above-mentioned steps 202 can specifically include：
Step 801, control network element send the first notification message, first notification message to M the first base station to be checked respectively It is used to indicate the first base station to be checked broadcast feature sequence on the predeterminated position of radio frames.
Specifically, control network element will send the first notification message to the first base stations to be checked the M determined respectively, and each first Base station to be checked is according to the notification message received, meeting broadcast feature sequence on the predeterminated position of radio frames.Wherein, radio frames Predeterminated position for example can be the areas GP of S subframes, it is, of course, also possible to for the other positions of radio frames.It needs to illustrate, If the first different base stations to be checked simultaneously broadcast feature sequence when, it will carried out on the designated position of different radio frames wide It broadcasts, such as：Such as first the base station B to be checked of base station A and first to be checked simultaneously broadcast feature sequence when, the first base station A to be checked is 801 The designated position of radio frames sends characteristic sequence, and the first base station B to be checked sends characteristic sequence in the designated position of 802 radio frames Deng.
Step 802, control network element send second notification message to the neighboring station of each first base station to be checked, and second notification message is used Neighboring station in the first base station to be checked of instruction receives characteristic sequence on the predeterminated position of radio frames.
Specifically, control network element is firstly the need of all neighboring stations for determining each first base station to be checked, in concrete implementation mistake Cheng Zhong, control network element can send query messages to each first base station to be checked, and the first base station to be checked will be according to the query messages, really It makes all with base station that is itself having syntople, and the carrying of the identification information of these neighboring stations is sent to control in feedback message Network element processed.In addition, if when control network element deployment is in webmaster, each the can also be directly inquired by configuration information on webmaster The neighboring station information of one base station to be checked.Determine that the concrete mode of the neighboring station of the first base station to be checked, the present embodiment exist for control network element This is not construed as limiting.
Network element is controlled according to the feedback message received, the base station corresponding to identification information sends second notification message.Respectively The neighboring station of first base station to be checked is according to the second notification message, it will receives characteristic sequence on the predeterminated position of radio frames.
Step 803, control network element receive the first response message that the neighboring station of each first base station to be checked is sent, the first sound respectively The neighboring station that message is used to indicate the first base station to be checked is answered whether to receive characteristic sequence.
Specifically, after the neighboring station of each first base station to be checked receives characteristic sequence on the predeterminated position of radio frames, it will To control network element feedback reception as a result, i.e. each neighboring station will send the first response message to control network element respectively, to notify control net Member its whether on the predeterminated position of radio frames receive characteristic sequence.
In addition, if the first base station A to be checked sends characteristic sequence in the designated position of 801 radio frames, the first base station B to be checked exists The designated position of 802 radio frames sends characteristic sequence, then the neighboring station of the first base station B to be checked of base station A and first to be checked is wireless 801 The designated position of the designated position of frame and 802 radio frames, to judge whether there is neighboring station to receive in the designated position of 801 radio frames Whether characteristic sequence has neighboring station to receive characteristic sequence etc. in the designated position of 802 radio frames.
If step 804, control network element determine that all neighboring stations of the first base station to be checked do not connect according to the first response message Characteristic sequence is received, then the first base station to be checked is determined as the second base station to be checked.
Specifically, the principle of clock stringent synchronization, the first base station to be checked is required to send in the areas S subframe GP according to TDD system After characteristic sequence, if the clock of all base stations is all synchronous, the neighboring station of the first base station to be checked can be normal in the areas S subframe GP Characteristic sequence is received, if the first base station clock step-out to be checked, the neighboring station of the first base station to be checked may connect because of missing Detection window is received, leads to not detect characteristic sequence.Therefore, if controlling what network element was sent according to the neighboring station of each first base station to be checked First response message determines that all neighboring stations of some the first base station to be checked do not receive first base station to be checked in radio frames Predeterminated position send characteristic sequence, then first base station to be checked can be determined as the second base station to be checked, subsequently to carry out It further confirms that.In addition, if when some first base station to be checked is the neighboring station of other the first base stations to be checked simultaneously, not only need to sentence Whether whether the neighboring station of disconnected first base station to be checked receives characteristic sequence, it is also necessary to judge its own in the default position of radio frames The place of setting receives the characteristic sequence that other first base stations to be checked are sent.
For example, if the first base station to be checked includes the base stations A, the base stations B and the base stations C, wherein the neighboring station of the base stations A is a bases It stands, the base stations b and the base stations c, the neighboring station of the base stations B is the base stations a, the base stations d and the base stations c, and the neighboring station of the base stations C is the base stations A, the base stations a, b bases It stands and the base stations d.When the base stations A, the base stations B and the base stations C respectively the predeterminated position of radio frames send characteristic sequence after, respective neighbour Characteristic sequence will be received in the predeterminated position of radio frames by standing, if the base stations neighboring station a, the base stations b and the base stations c of the base stations A be not in nothing Characteristic sequence is received on the predeterminated position of line frame, and the base stations A are also not received by the characteristic sequence of the base stations C transmission, then by A bases Station is determined as the second base station to be checked.
The method of the second base station to be checked of determination provided in this embodiment, since each first base station to be checked is respectively in radio frames Characteristic sequence is sent on predeterminated position, control network element will determine that all neighboring stations of each first base station to be checked whether in radio frames This feature sequence is received on predeterminated position, if the first base station clock step-out to be checked, the neighboring station of the first base station to be checked may Because missing reception detection window, lead to not detect characteristic sequence, it is possible thereby to determine the second base to be checked of possible step-out It stands, so that the determination of the second base station to be checked is more accurate.
Optionally, Fig. 9 is the flow diagram that control network element provided by the embodiments of the present application determines the second base station to be checked, this In embodiment determine the second base station to be checked mode and Fig. 8 in determine the second base station to be checked mode between difference lies in, this Each first base station to be checked sends characteristic sequence, and the neighboring station of each first base station to be checked on the predeterminated position of radio frames in embodiment After receiving characteristic sequence on the predeterminated position of the radio frames, whether neighboring station will receive the result of characteristic sequence and feeds back to the One base station to be checked, and judge whether all neighboring stations receive characteristic sequence by the first base station to be checked, thereby determine that the second base to be checked It stands, and the identification information of the second base station to be checked is sent to control network element.As shown in figure 9, above-mentioned steps 202 can specifically wrap It includes：
Step 901, control network element send the first detection message to M the first base station to be checked respectively, the first detection message It is used to indicate the first base station to be checked and sends characteristic sequence on the predeterminated position of radio frames.
Specifically, control network element can send the first detection message to M the first base station to be checked respectively, which disappears The mapping relations between the identification information of base station and radio frames are carried in breath.Each first base station to be checked is according to first received Message is detected, searches all neighboring stations of our station, and send a notification message to all neighboring stations, which is used to indicate neighboring station Characteristic sequence is received on the predeterminated position of radio frames.In addition, each first base station to be checked is according to the identification information of base station and wireless Mapping relations between frame determine the radio frames corresponding to the identification information of itself, namely determine from which radio frames Predeterminated position on send characteristic sequence, when each first base station to be checked sends feature on the predeterminated position for the radio frames determined After sequence, all neighboring stations of our station will receive characteristic sequence on the predeterminated position of corresponding radio frames, and all neighboring stations will To the first returning response message in base station to be checked, the result letter whether neighboring station receives characteristic sequence is carried in the response message Breath, the result information that the first base station to be checked carries in message according to response, determines the second base station to be checked.In concrete implementation process In, if the first base station to be checked message according to response, determines all neighboring stations of our station not in the default position of corresponding radio frames It sets and receives characteristic sequence, then the first base station to be checked is determined as the second base station to be checked.
Step 902, control network element receive the first feedback message that M the first base station to be checked is sent respectively, first feedback Message includes the identification information for each second base station to be checked that the first base station to be checked is determined.
Specifically, the mark of the second base station to be checked is believed after determining the second base station to be checked in each first base station to be checked Breath carries and is sent to control network element in the first feedback message.Wherein, if all neighboring stations of our station are determined in the first base station to be checked Characteristic sequence is had received on the predeterminated position of radio frames, then illustrates that the clock of the first base station to be checked does not have step-out, at this point, First base station to be checked can not have to send the first feedback message or the first base station to be checked to control network element transmission to control network element Control message in do not carry the identification information of any base station.
Step 903, control network element determine the second base station to be checked according to identification information.
Specifically, control network element is after receiving the first feedback message that the first base station to be checked is sent, by the first feedback Base station corresponding to identification information in message is determined as the second base station to be checked.In addition, if control network element is not received by first and waits for The first feedback message that base station is sent is examined, or does not carry the identification information of any base station in the first feedback message received When, the second base station to be checked is not present by determining, at this point, the clock of the first base station to be checked is in synchronous state.
The method of the second base station to be checked of determination provided in this embodiment, since each first base station to be checked is respectively in radio frames Characteristic sequence is sent on predeterminated position, and judges whether all neighboring stations receive feature sequence on the predeterminated position of the radio frames Row, thereby determine that whether itself is the second base station to be checked, the result to will determine that out is sent to control network element, it is possible thereby to carry The efficiency that high second base station to be checked determines.
Step 204, control network element determine the base station of step-out from P the second base stations to be checked.
In the present embodiment, control network element will pass through the side of silence detection after determining P the second base stations to be checked Formula determines the base station of step-out.Since control network element on the predeterminated position of radio frames by sending and receiving characteristic sequence, with And the mode of silent detection, the base station of step-out is finally determined, so as to improve the accuracy of step-out determination.
Optionally, Figure 10 is that control network element provided by the embodiments of the present application determines step-out from P the second base stations to be checked The flow diagram of base station, as shown in Figure 10, above-mentioned steps 203 can specifically include：
Step 1001, control network element send third notice message to the second base stations to be checked P successively, and to the second base to be checked The neighboring station stood sends the 4th notification message, wherein control network element sent in the neighboring station for receiving i-th of second base stations to be checked the After two response messages, third notice message is sent to the second base station to be checked of i+1, and to the second base station to be checked of i+1 Neighboring station send the 4th notification message.
Wherein, which is used to indicate each second base station to be checked and is in silent status in default radio frames, 4th notification message is used to indicate neighboring station and carries out Interference Detection, the second response message when the second base station to be checked is in silent status Be used to indicate when the described second base station to be checked is in silent status, the neighboring station of each second base station to be checked detect itself by Interference whether change.
Specifically, control network element will send third notice message to the second base stations to be checked P successively, and to the second base to be checked The neighboring station stood sends the 4th notification message, and i-th of second base stations to be checked, will be in default nothing after receiving third notice message Silent status is on line frame, wherein default radio frames can be several continuous radio frames, such as indicate that the second base station to be checked exists It can also be several discontinuous radio frames in silent status etc. in 2nd radio frames to the 7th radio frames, such as indicate Second base station to be checked is in silent status in the 2nd radio frames, the 4th radio frames, the 6th radio frames and the 7th radio frames Deng.
In addition, control network element can also send the 4th notification message to the neighboring station of the second base station to be checked, to indicate that this second is waited for All neighboring stations of base station are examined in default radio frames, i.e., the second base station to be checked carries out Interference Detection when being in silent status.Citing For, if some second base station to be checked is in silent status, second base station to be checked in the 2nd, the 4th, the 6th and 7 radio frames All neighboring stations will postpone several seconds after carry out Interference Detection, with ensure neighboring station first carry out detect and continue it is entire silent possible Period, to improve the accuracy of Interference Detection.In practical applications, the neighboring station of the second base station to be checked receives the 4th notice and disappears Breath, and after postponing several seconds will carry out uplink interference detection in each radio frames and carry out the matching of silent collection of illustrative plates, to sentence Whether disconnected interference variations meet silent collection of illustrative plates when the second base station to be checked executes silent.
After the neighboring station of i-th of second base stations to be checked, which detects, to be completed, the second response message can be sent to control network element, with Notice control network element, when second base station to be checked is in silent status, whether the interference suffered by itself changes.Control The second response message that network element is sent in the neighboring station for receiving i-th second base stations to be checked and then to be checked to i+1 second Base station sends third notice message, and sends the 4th notification message to the neighboring station of i+1 the second base station to be checked, i+1 the The neighboring station of two base stations to be checked will carry out Interference Detection, and to control reported by network elements testing result, and so on, until completing P The detection of a second base station to be checked.
In practical applications, uplink interference detection is carried out in each radio frames when neighboring station, and carries out of silent collection of illustrative plates With later, if interference variations meet silent collection of illustrative plates, i.e., when the second base station to be checked is in silent status, neighboring station during this period by To interference variation (interference decline duration synchronous with the second silence holding in base station to be checked with the frequency) also has occurred, then neighboring station general Record currently meets first radio frame number of silent collection of illustrative plates, and (or n-th, the application do not limit, as long as all base stations are protected Hold consistent), and the carrying of the radio frame number of record is sent to control network element in the second response message.
Step 1002, control network element determine the base station of step-out according to the second response message.
Specifically, since interference is caused by send out work(in incorrect sequential as the base station of step-out, control network element According to the second response message, if determining, the base station of step-out includes controlling network element according to the second response message, determines that second is to be checked When being in silent status in default radio frames, the neighboring station of each second base station to be checked detects dry in default radio frames for base station It disturbs and changes, then the second base station to be checked is determined as to the base station of step-out.Namely the if silent all downlinks in the second base station to be checked After subframe, interference due to adjacent station is eliminated, then can determine that second base station to be checked is the base station of step-out；If the interference of its neighboring station does not have There is elimination, then second base station to be checked is synchronous base station.During concrete implementation, control network element is receiving the second sound After answering the radio frame number carried in message, the radio frames that two neighboring stations with the presence or absence of some the second base station to be checked report are will determine that Number effectively and difference is less than or equal to 1, if judging to exist, the radio frame number that reports of two neighboring stations is effective and difference is less than Or when equal to 1, it will determine that second base station to be checked is the base station of step-out.In addition, after determining the base station of step-out, control network element is also Warning information will be sent out, and self-healing operation is executed to the base station of step-out, to prevent the base station of step-out to other adjacent co-frequency cells It interferes.For example, if some second base station to be checked is in silent status in the 2nd, the 4th, the 6th and 7 radio frames, and Interference is eliminated when the neighboring station of second base station to be checked is detected from N, N+2, N+4 and N+5 radio frames, at this point, It will then determine that the second base station to be checked is the base station of step-out.It should be noted that since the second base station to be checked is likely to be in step-out State, therefore, the 2nd radio frames of the second base station to be checked are not necessarily the 2nd radio frames of neighboring station, as long as therefore neighboring station detection come from Interference variations suffered by body meet silent collection of illustrative plates, it is not required that radio frames are consistent.
Step-out provided in this embodiment determines method, since the second base station to be checked executes downlink silence in default radio frames Afterwards, neighboring station will be preset at this and carry out Interference Detection in radio frames, to judge when the second base station to be checked is in silent status, oneself Whether the interference suffered by body changes, if control network element judges that the neighboring station of some the second base station to be checked presets radio frames at this Upper suffered interference is changed, and changing rule meets the silent collection of illustrative plates of the second base station to be checked, then can determine this Second base station to be checked is the base station of step-out, so as to improve the accuracy of step-out determination.
Optionally, Figure 11 is the another flow signal for the base station that control network element provided by the embodiments of the present application determines step-out Figure, determine in the present embodiment the base station of step-out mode and Figure 10 in determine step-out base station mode between difference lies in, Each second base station to be checked is in silent status in default radio frames in the present embodiment, and the neighboring station of each second base station to be checked is at this The interference suffered by itself is detected in default radio frames, and the result detected is fed back into the second base station to be checked, is waited for by second Inspection base station judges whether the interference that its all neighboring stations detect changes, and thereby determines that the base station of step-out, and by step-out The identification information of base station is sent to control network element.As shown in figure 11, above-mentioned steps 203 can specifically include：
Step 1101, control network element send the second detection message to P the second base station to be checked successively, wherein control network element After receiving the second feedback message that i-th of second base stations to be checked are sent, second is sent to the second base station to be checked of i+1 Message is detected, which is used to indicate the second base station to be checked and is in silent status in default radio frames, and second is anti- Feedback message includes the identification information of the base station for the step-out that the second base station to be checked is determined.
Specifically, control network element will be sent out to each second base station to be checked successively after determining P the second base stations to be checked The second detection message is sent, to indicate that the second base station to be checked is in silent status in default radio frames.Wherein, control network element will be Receive the second feedback message and then send second to the second base station to be checked of i+1 that i-th of second base stations to be checked are sent Message is detected, to be detected in turn to each second base station to be checked.
Specifically, the second base station to be checked will determine according to the second detection message and lose after receiving the second detection message The base station of step, wherein the base station of step-out is the base station for meeting testing conditions, which is to be in quiet in the second base station to be checked When silent state, the interference that the neighboring station of the second base station to be checked detects changes.During concrete implementation, the second base to be checked It stands and determines the base station of step-out according to detection message, including：Second base station to be checked sends a notification message to all neighboring stations, which disappears Breath is used to indicate neighboring station and detects the interference itself being subject to when the described second base station to be checked is in silent status；Second base station to be checked It will be set as silent status in default radio frames；Second base station to be checked receives the response message that each neighboring station is sent, and according to sound Message is answered to determine the base station of step-out, which is used to indicate when the second base station to be checked is in silent status, and each second waits for Whether the interference that the neighboring station of inspection base station detects changes.Specifically, if the second base station to be checked message according to response, is determined When second base station to be checked is in silent status in default radio frames, each neighboring station of the second base station to be checked is examined in default radio frames The interference measured changes, then the second base station to be checked is determined as to the base station of step-out.
During concrete implementation, for each the second base station to be checked, schemed according to silence after postponing several seconds Spectrum, i.e., execute downlink silence in default radio frames, and the neighboring station of second base station to be checked will carry out uplink in each radio frames Interference Detection, and collection of illustrative plates matching is carried out, to judge whether interference variations meet silent figure when the second base station to be checked executes silent Spectrum.If interference variations meet silent collection of illustrative plates, i.e., when the second base station to be checked is in silent status, what neighboring station was subject to during this period Interference is also changed, then neighboring station will record current radio frame number, and the radio frame number of record is carried in response message In be sent to the second base station to be checked.After the radio frame number that second base station to be checked carries in receiving response message, will determine that is The no radio frame number reported there are two neighboring stations is effectively and difference is less than or equal to 1, if judging, there are two neighboring stations to report Radio frame number effectively and difference be less than or equal to 1 when, will determine the second base station to be checked be step-out base station, and by itself Identification information is carried is reported to control network element in the second feedback message.
Step 1102, control network element determine the base station of step-out according to identification information.
Specifically, base station corresponding to identification information is determined as step-out by control network element according to the identification information received Base station in addition, control network element will also send out warning information to the base station of step-out, and executes self-healing operation to the base station of step-out, with Prevent the base station of step-out from being interfered to other adjacent co-frequency cells.
Step-out provided in this embodiment determines method, since the second base station to be checked executes downlink silence in default radio frames Afterwards, neighboring station will be preset at this and carry out Interference Detection in radio frames, to judge when the second base station to be checked is in silent status, oneself Whether the interference suffered by body changes, if the second base station to be checked judges that its neighboring station presets suffered in radio frames do at this It disturbs and is changed, then can determine that its own is the base station of step-out, and will determine that result is sent to control network element, so that control Network element executes self-healing operation to the base station of step-out, it is possible thereby to improve the efficiency of step-out determination.
Step-out provided in this embodiment determines method, the interference index sent by receiving N number of base station, and is referred to according to interference Mark from determining M the first base stations to be checked in the neighboring station of N number of base station and/or N number of base station, and determines P the second base stations to be checked, In, P the second base stations to be checked are the base station for meeting testing conditions selected from M the first base stations to be checked, wherein detector bar Part cannot be received by neighboring station in designated position for the characteristic sequence that the first base station to be checked is broadcasted in the designated position of radio frames, then The base station of step-out is determined from P the second base stations to be checked.Since the interference index that control network element is reported according to base station first selects M A first base station to be checked, it is wireless at this further according to whether neighboring station can receive the first base station to be checked in the designated position of radio frames The characteristic sequence that the designated position of frame is sent finally determines step-out to select the second base station to be checked for meeting testing conditions Base station, due to gradually reduced by different modes step-out base station determine range, so as to improve step-out determination Accuracy.
